Definitions
- the invention relates to a device for spraying disperse systems.
- a cleaning element is slidably mounted which, at the same time is connected to a tip which in a relative movement of the cleaning element to the spray head can slide into an opening of the hole type nozzle to clean this opening (French Patent No. 569,852). In such case, the cleaning is to follow without interruption of the normal function of the spray head.
- a spray valve for spraying viscous liquids which is designed as a needle valve, is known (U.S. Pat. No. 2,794,683).
- a perforated disk is placed in a spray head of such needle valve concentric to its opening before the hole type nozzle.
- a plunger, slidable inside of the spray head has on its head end a cylindrical or conical section which can be shoved through the perforated disk into the opening of the hole type nozzle to press dirt accumulation from such opening of the hole type nozzle.
- the main object of the invention is to provide a simply-designed, easily-cleanable and quickly-interchangeable device by which disperse systems, which contain coarse-grained materials or polymers tending to gum, can be sprayed without reduction of the throughput over a considerable period.
- This main object is achieved according to the invention by the design of the invention device for spraying with the features indicated herein (and by the invention process).
- the invention involves a device for the spraying of disperse systems.

- Plunger (1) has one or more ducts for the disperse system which, going from the coupling side of the plunger through the plunger, comes out into hollow space (2) of spray head (5).
- the device according to the invention is used for spraying disperse systems, preferably suspensions, containing graphite in an upper grain size of 25 to 150 microns as the disperse phase and a liquid as the dispersing agent.
- Such suspensions especially those that, besides the dispersing agent, also contain portions of stabilizers, dispersion auxiliary agents and polymers, for example, according to German OS 2,450,716, were able to be sprayed poorly when spraying rollers with known devices.
- the plunger exhibits, axially to the coupling side, an intake duct (3) for the disperse system, from which one or more output ducts (4) branch off toward the nozzle side end.
- output duct or ducts (4) are placed branched at an angle to intake duct (3) so that the disperse system radially to tangentially strikes the inside wall of spray head (5) configured as hollow space (2) or offset parallel to the axis to intake duct (3) so that the disperse system axially strikes the inside wall of spray head (5) configured as hollow space (2).
- plunger (1) exhibits one or more ducts (6) which, starting from the coupling side of the plunger offset parallel to the axis running through the plunger laterally to the plunger tip, comes out into hollow space (2) of spray head (5).
- the nozzle side end of plunger (1) exhibits a conical shape with an angle of taper of 15° to 90° and the inside of hole type nozzle (7) is matched to the plunger tip and the plunger, in its longitudinal direction, is configured to be movable by a spring (8) so that during the spraying process it is pressed back by the spraying pressure from spray head (5) and as soon as the spraying pressure drops to an undesired volume it is shoved permanently in front of the opening of hole type nozzle (7).
- coupling (9) is designed as a holder of the spray device.
- coupling (9) axially exhibits a passage duct (10) for the disperse system and is connected either axially or radially to housing (11) of the spray device.
- coupling (9) is designed as a screw or plug coupling, preferably as a plug coupling.
- the invention also involves a process for using the invention device for spraying of rollers during the hot rolling of sheets, hollow sections and other shapes, with a graphite-containing dispersion which contains graphite having a grain size of 50 to 150 microns.
- FIG. 1 is a partial axial section through a first embodiment of the device of the invention
- FIG. 2 is a partial axial section through another embodiment of the device of the invention with a modified guiding of the outlet ducts in the plunger;
- FIG. 3 is a partial axial section through another embodiment of the device of the invention with a modified guiding of the ducts in the plunger;
- FIG. 4 is a partial axial section through another embodiment of the device of the invention with a modified guiding of the ducts in the plunger;
- FIG. 5 is a partial axial section through another embodiment of the device of the invention with radial connection of the coupling to the plunger device;
- FIG. 6 shows a partial axial section of a variation of the embodiment according to FIG. 5 not belonging to the invention.
- plunger (1) which is movable in the longitudinal direction by means of spring (8), is placed in housing (11) which, on one side, is connected to spray head (5) and, on the opposite side, to coupling (9).
- Plunger (1) on the coupling side has intake duct (3) for the disperse system, from which two output ducts (4) branch off toward the nozzle side end, according to FIG. 1.
- the number of output ducts can vary between one and ten, preferably between three and six.
- Output ducts (4) are preferably designed as bores with diameters suitably between 0.5 and 3 mm.
- Output ducts (4) in this case can be placed, e.g., according to FIG. 2, at a right angle relative to the axis of the spray device, at any angle to the axis, e.g., according to FIG. 1, or offset parallel to the axis according to FIG. 4 .
- these ducts designed as bores it can be achieved that the disperse system radially to tangentially or axially strikes the inside wall of spray head (5) configured as hollow space (2).
- one or more, suitably one to ten, preferably three to six, ducts (6) are provided which, starting from the coupling side of the plunger laterally to the plunger tip, come out into hollow space (2) of spray head (5).
- these ducts are designed as bores whose diameters vary between 0.5 and 3 mm.
- the nozzle side end of plunger (1) exhibits a conical tip.
- the angle of taper is suitably 15° to 90° .
- Hole type nozzle (7) toward the housing inside is matched in its shape to plunger (1).
- the opening of hole type nozzle (7) can have the shape of a flat section or circular section jet.
- the diameter of the nozzle is adjusted to the desired throughput and spray pattern and suitably is 0.3 to 4 mm.
- Plunger (1) is designed to be movable in its longitudinal direction by spring (8) so that during the spraying process it is pressed back by the spraying pressure from spray head (5) and, as soon as the spraying pressure drops to an undesired volume, it is shoved permanently in front of the opening of hole type nozzle (7).
- Coupling (9) is suitably designed as a plug or screw coupling and suitably exhibits axially a flow duct (10) for the disperse system.
- Coupling (9), according to FIGS. 1 to 4 can be connected axially to the spray device or, according to FIG. 5, radially to the spray device. If, according to the configuration of FIG. 5, coupling (9) is radially connected to the spray device, according to FIG. 6, the disperse system can be guided directly into hollow space (2) of spray head (5) without passing through ducts of the plunger.
- Coupling (9) preferably is used at the same time as a holder of the spray device.
- a plug coupling is used which is configured so that, with a handle, it can be inserted with a radial movement into counterhousing (12) o supply element (13) and be radially locked.
- the spray device is supplied with the disperse system by supply element (13), which is configured as a supply pipe or distributor with pump devices known in the art.
- the pressures used in this case are in the range of 5 to 100 bars, suitably between 20 and 80 bars.
- Coarse-grained materials and polymers tending to gum can be sprayed without reduction of the throughput with the device according to the invention.
- the plunger is briefly pressed from the hollow space in the spray head on the hole type nozzle, by which particles possibly clogging the hole type nozzle are pressed out through the latter. After the retraction of the plunger, the hole type nozzle is again fully operative.
- Hole type nozzles with nozzle openings of 0.5 to 1.0 mm are used for such suspensions.
- the spray device can also be used for other known disperse systems which, for example, on contact with the air tend to gum, or because of the particle size of the disperse phase thus far have been able to be sprayed poorly or not at all with known devices.
- the plunger can be controlled so that, after stopping of the feeding of the disperse system, it is pressed into the hole type nozzle, thereby at the same time cleaning and securely sealing the hole type nozzle. With a renewed feeding of the disperse system, the plunger can again be retracted into the spray head.
- the device according to the invention is used especially for spraying of graphite-containing dispersions containing graphite with a grain size of 25 to 150 microns, during the hot rolling of sheets, sections and other shapes.
